Abstract

Solid-state fluorescent compounds have potential applications for emitters in OLED, 1, 1a, 1b and 1c solid dye laser, 2, 2a and 2b and sensors. 3 However, the fluorescence intensity in the solid state is generally low due to stronger interactions in the condensed and solid state. To improve this point, introduction of bulky substituent(s) into the fluorophores 4, 4a and 4b and preparing the fluorophores enclathrating guest molecule(s) are considerable. In the latter case, the ...
